Art. 65. Any general officer commanding an army, or colonel commanding a separate department, may appoint general courts martial whenever necessary. But no sentence of a court martial shall be carried into execution until after the whole proceedings shall have been laid before the officer ordering the same, or the officer commanding the troops for the time being; neither shall any sentence of a general court martial, in time of peace, extending to the loss of life, or the dismission of a commissioned officer, or which shall, either in time of peace or war, respecting a general officer, be carried into execution, until after the whole proceedings shall have been transmitted to the secretary of war, to be laid before the President of the United States, for his confirmation or disapproval and orders in the case. All other sentences may be confirmed and executed by the officer ordering the court to assemble, or the commanding officer for the time being, as the case may be. Art. 66. Every officer commanding a regiment, or corps, may appoint, for his own regiment or corps, courts martial, to consist of three commissioned officers, for the trial and punishment of offences, not capital, and decide upon their sentences. For the same purpose all officers, commanding any of the garrisons, forts, barracks, or other places where the troops consist of different corps, may assemble courts martial, to consist of three commissioned officers, and decide upon their sentences. Art. 67. No garrison, or regimental court martial shall have the power to try capital cases, or commissoned officers; neither shall they inflict a fine exceeding one month’s pay, nor imprison, nor put to hard labor, any non-commissioned officer or soldier, for a longer time than one month. Art. 68. Whenever it may be found convenient and necessary to the public service, the officers of the marine shall be associated with the officers of the land forces, for the purpose of holding courts martial and trying offenders belonging to either; and in such cases the orders of the senior officers of either corps who may be present and duly authorised, shall be received and obeyed. Art. 69. The judge advocate, or some person deputed by him, or by the general, or officer commanding the army, detachment, or garrison, shall prosecute in the name of the United States, but shall so far consider himself as council for the prisoner, after the said prisoner shall have made his plea, as to object to any leading question to any of the witnesses, or any question to the prisoner, the answer to which might tend to criminate himself; and administer to each member of the court before they proceed upon any trial, the following oath, which shall also be taken by all members of the regimental and garrison courts martial.
